Join us to learn about the best approach to building resilient applications using three innovative technologies—chaos Engineering, Observability, and AIOps.

Explore how:
✔️ Chaos Engineering aids in pinpointing potential failure points in complex systems by deliberately inducing problems and observing their effects.
✔️ Observability and troubleshooting platforms enhance this approach in microservices environments by providing extensive insight into the internal states of systems operating in cloud-native environments.
✔️ The significance of integrating technology and personnel beyond mere alerts through AIOps, which provides automated diagnostics with human-led resolution.

Streamline the onboarding process with the new project application in Argo CD thanks to the introduction of ArgoCDApps Helm chart. This robust tool empowers users to effortlessly oversee additional Argo CD applications/projects, paving the way for seamless automation of the onboarding process and enhancing overall efficiency. Consider the widespread usage of Argo CD and the pivotal role it plays in orchestrating smooth application deployment to scale and cater to diverse teams. 

Prometheus Blackbox Exporter is a valuable tool for monitoring external systems and services, probing endpoints using protocols like HTTP, HTTPS, ICMP, DNS, and returning metrics about their health and performance. Key benefits include supporting multiple protocols, customizable probes, rich metrics for analysis, seamless integration with Prometheus, proactive alerting capabilities, increased visibility into dependencies, reduced downtime, improved service quality, and expedited issue resolution. Organizations looking to enhance monitoring environments and ensure application reliability can benefit greatly from using Blackbox Exporter.

The KCNA certification is a good entry point for beginners interested in cloud native technology, providing foundational knowledge on implementing containers in a vendor-neutral way. The exam is considered to be at a pre-professional level of difficulty and is a great first step into the world of Kubernetes and cloud native technology. Candidates can expect multiple-choice questions in a supervised online testing environment, where they must demonstrate basic knowledge of Kubernetes and cloud native technology concepts.

This year, Europe’s flagship conference on everything cloud native will take place from September 03-04, 2024.

As in the past editions, ContainerDays 2024 will offer you a great learning experience on #Kubernetes, #CloudNative, #DevOps, #GitOps, #EdgeComputing, and much more. This is your opportunity to meet and exchange with other cloud native enthusiasts from across the globe in person or in the virtual world.

Nowadays, one should absolutely respect these rules:
1) Building a microservice distributed system without proper monitoring/observability tools can be challenging as it may be hard to identify the root cause of bottlenecks.
2) Understanding the basics of distributed systems, such as how they consist of multiple integrated components working together towards a common goal, is essential for efficient tracing and monitoring.
3) Distribute tracing in a distributed system is crucial for measuring performance, identifying bottlenecks, and ensuring a seamless user experience.

Pod startup time is crucial for application performance and user experience. This blog post details how VolumeSnapshots were used to reduce startup times by 83% in AWS environments at Riskified. VolumeSnapshot is a Kubernetes feature that captures and restores application volumes, improving application start time, data consistency, data recovery, backup and restore efficiency, data versioning, and automation capabilities.

Understand how circuit breakers work in event-driven architectures, including the stateful checks and handling of slow requests. Implementations in serverless architectures, like using Elasticache for state storage, are discussed. Recommended resources for further reading and considerations for high-throughput systems are also highlighted.

AWS OnDemand vs AWS Reserved Instances: The infrastructure costs can skyrocket with AWS OnDemand, while switching to a serverless architecture can cut costs significantly. The potential for cost savings with AWS serverless setups is clear. It's important to carefully consider all options to optimize costs in the long run.

Application servers like RoadRunner use long-lived PHP processes to handle multiple requests without constantly bootstrapping new execution environments, reducing overhead and improving performance. This tutorial will guide you through developing a PHP application on RoadRunner, explaining its setup, operation, and integration with PHP applications for improved performance.

This guide details a GitOps-based CI/CD pipeline on GitHub Actions for SOC 2 compliance, with an emphasis on simplicity and developer experience. The workflow includes automated testing, artifact publishing, and infrastructure deployment controlled through pull requests.

This article describes the recent feature enhancement to Cloud Run allowing Cloud Storage bucket to be mounted as a Container volume. With the introduction of Cloud Storage mounts in Cloud Run, you can now mount Cloud Storage buckets as volumes within Cloud Run containers without utilizing additional libraries. This feature enables connecting serverless Cloud Run workloads directly to static assets within Object store backends, eliminating the need for cloud client libraries and third-party services.

In 1980, the first gigabyte-sized hard disk drive was introduced by IBM. The IBM 3380 was as large as a refrigerator and weighed about 550 pounds, but it could store a whopping 2.52 gigabytes of data. At the time, this storage capacity was enormous, costing over $40,000, which translates to an astonishing $15,000 per gigabyte.

“The best programs are written so that computing machines can perform them quickly and so that human beings can understand them clearly. A programmer is ideally an essayist who works with traditional aesthetic and literary forms as well as mathematical concepts, to communicate the way that an algorithm works and to convince a reader that the results will be correct.”
